IMPROVEMENT IN REGULATING-COCKS.

Specification forming part of Letters Patent No. 142,521, dated September 2, 1873; application led June 20, 1873.

To all whom it may concern:

Be it known that we, CHARLES E. SEAL, of Winchester, in the county of Frederick and State of Virginia, and EDWIN YF. BROOKS, of the cityof Baltimore and State of Maryland, have invented a new and useful Improvement in Gut-Off and Regulating-Cock for Water; and we do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing forming a part of this specification.

This invention has for its object to place under perfect control the Water-supply of buildings by an improved form of cock and operatin g devices designed to permit the cock to be opened or closed at a point removed from l the main or supply pipe. The invention relates to water-regulatorstand cut-OES where the waste-valve is operated by the main valve 5 and consists in combining a 'sliding main valve with the waste-valve, so that both can be simultaneously operated from a distant chamber of a building, as hereinafter described and claimed.

Figure l is a detail face view of the valveoperating mechanism. Fig. 2 is a sectional view of the cock, and Fig. 3 is a view illustrating the cock-and-valve-operating devices.

The cock proper is composed .of a shell, A, which is at one end provided with a screwthreaded prolongation, B, for attachment to the service or distributing pipe, and at the other end with an internally-threaded socket, C, for the reception of the main or supply pipe. The cock is provided-with aninternal valve-Seat, D, which serves also to divide the shell of the cock into two compartments. Into an opening in the top of the cock there is screwed a cap-tube, E, through which operates the stem F of the valve G. Said valve is of a conical form, with a horizontal disk portion suitably packed to render it watertight, and inserted when the water-supply is to be shut off into its seat in the valve-chamber. The stem of the valve is encircled by a spiral Spring, H, which serves to return the valve to its seat after the upward pressure upon the same has been removed, retaining 1t` in this position firmly for insuring a watertight joint. A concave-surfaced plug or packing washer, I, is arranged upon the valvestem, for effecting, in connection with'a iixed corresponding projection on the inner top surface of the cap-tube, a tight joint at that junctionr To the chamber of the cock, communicating with the service or distributing pipe, thereis attached a pendent tube, J, containing a valve, K, which is impelled or projected into the opening or seat in the bottom of the cock-chamber by a spiral sprin g, L, encircling the stem L of said valve.

When the supply-valve is open and the iiow of water through the cock going on, the valve K is held in a closed position by the spring for preventing the discharge of water through the tube J but as soon as the downward or closing movement ofthe supply-valve takes place, the recessed end of the latter will be entered by the conical end of the valve K, thus forcing the latter from its seat and opening the communication between the tube J and cock-chamber. This operation will permit all the surplus water remaining in the servicepi'pe and cock to escape through the tube J, thus preventing all freezing by keeping the pipes perfectly dry. 'A packing ring or disk, a, below the conical portion of the valve K, hasits edge serrated or notched, so as to permit the downward passage of the Water between said ring and the inner surface of the waste-tube.

In order to enable the Water-supply of a building to be shut off at the tjunction of the supply with the service-pipes by an operator stationed at a remote point in the building, it is proposed to attach to the valve-stem a rod, chain, or equivalent device, M, which extends into one or more rooms, where we locate a pivoted lever-handle, N, vibrating on a horizontal axis, and provided with a lateral extension or elbow, O, to which the connectingrod is attached. The lever-handle N is combined or arranged within a quadrantal boX or case, P, the handle portion projecting through the open top of the latter. By moving the lever-handle in the proper directions, the valve in the supplycock can be opened to a greater or less degree for regulating the quantity of water passing into the service pipe. The valve is retained in position when open, in order to overcome the pressure of its spring, by a thuml)-catol1, Q, pivoted to the lever-handle, and combined with a spiral spring, R, which holds the toe or beak of the catch in contact with one of a series of ratchet-teeth, S, formed on the upper portion of the box P. Said box is suitably inscribed with characters indicating the direction for turning the lever-handle in opening or closing the valve.

From the above description it will be apparent that by shutting off the supply of water at the junction of the main and service pipe, instead of in the service-pipe, as heretofore, all accumulation of water in the latter is avoided, which, for various obvious reasons, is a desirable result.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination, with an upwardly springpressed waste-valve, K, and a downwardly spring-pressed mainvalve, G, the latter opening the former on its downward movement, of thesliding stem F, connection M, and lever N, arranged and applied as and for the purpose described.
